1. It's not just the bomb...

It's the delivery system for the bomb and its proximity to Israel. Iran may have a better capacity to develop a delivery system? Otherwise, I would tend to agree that Pakistan having the bomb is worse.

3. Doesn't take much of a delivery system for Pakistan to bomb India or some of its other neighbors.

Iranians that I have known have been, however, still very aware of the way that the US meddled to end their first democracy. I think it was Kermit Roosevelt who intrigued to topple Mosadegh in Iran. We have yet to live that down. So, Iran is especially a problem, even a danger for the US. It isn't just related to Israel.
